The official effective date for all recruitment and placement actions, as well as other personnel actions, shall be established by the Human Resources Division except in the case of resignation, the date of which is established by the employee who is resigning. Effective dates are not made on a retroactive basis. LBJ-ASMCA division management should, therefore, make every effort to initiate personnel actions enough ahead of time to meet the effective date requested (which may be noted under “Remarks” on the request for personnel/payroll action form). Effective dates for appointments can only be established after the pre-requisite medical, police and immigration clearance have been obtained by the Human Resource Division. Retroactive effective dates are only set when an administrative error has occurred or an appeal’s action results in retroactive corrective action.
